OVEN.

SPECIFICATION forming part of Letters Patent No. 336,937, dated March 2, 1886.

Application fill d March 23, 1885. Serial No. 159,826, (No model.)

To all whom, it ina/ 7j con/cern:

Be it known that I, WILLIAM MILLER@- citizen of the United States, residing at Grand 'Rapids, in the county ot' Kent and State of Michigamhave invented certain new and useful Improvements in Ovens for Oil, Gas, and Gasoline Stoves; and I do declare the following to be a full, clear, and exact description of the invention, suoli as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, and to theletters and gures of reference marked thereon, which form a part of this specification.

Figure l is a cross-section of the oven on thel line Y Y ot' Fig. 2. Fig. 2 is a cross-section of same on line X X of Fig. 1. Fig. 3 is a view ofsaid oven in perspective.

Similar letters refer to similar parts thronglr out the several views.

My invention relates to improvements in ovens for gas, gasoline, or oil stoves; and the objects of my improvements are, first, to con- Y centrate the heat or flame within a central iue by means ofa cone placed over the burner; second, to temper the heat upon the bottom of the oven by providing a false bottom; third, to distribute the heat by means of nues at the sides, thus delivering the heat at the top ofthe oven; fourth, to distribute the heat over the false bottom by means of an inverted cone placed between the false and true bottoms immediately over the flame.

I describe my invention as follows: In the bottom of the oven B, I construct the coneshaped opening J, to receive the heat from the burners, and. within said oven I build the ue I, running to the sides of the oven,where are attached the fines D D, opening into the top of the oven, as shown in Fig. 2. Thefalse bottom F, suitably supported by lugs or other device at the sides, has in the center the inverted cone G, resting on the Hue I, where it serves a double purpose: lirst7 as a central support to the false bottom, and last and chietiy, to divide and distribute the heat evenly throughout the air-chamber H. The heat being received in the flue I, is carried to the sides and discharged into the top`of the oven through the liues D D, and falling passes out through the Ventilating-holes a c. The

other parts shown are the handles A, the

grates C E, the supports to the same, numoercd l l, and the door K.

The above-described method of construction secures concentration of heat by causing a strong draft through the conical opening J, and a rapid distribution of same through the tlues D D, and also secures an equal distri- VVILLI'AM MILLER.
